We've only had aircrafts for a hundred years, and yet look at us. So, I've become absolutely fascinated by this strange, bizarre world of airports, air travel and transportation. It's interesting.

I love being in America. I love America. I absolutely adore working in America. I'm at my happiest when I'm in the States.

I've always been a bit of a dreamer. I've always loved to look and seek, and explore and find out.

Yeah. Science doesn't end. That's the one thing I learned. People think of science as spitting out right answers, and that's it. It's always under review.

Those people who are scared of science or are a bit dismissive of science tend to not really understand what science really is, which is the most beautiful, most elegant and most creative way of looking at the world.

The thing I loved, particularly, was the mystery of science and the idea that science doesn't know all the answers, but it is a process of finding out. It's not like science will give you the right answer and science knows everything. I love the mysteries of it.

Newton had a very good description of gravity, back in the day, and then Einstein came along and dug a little bit deeper. Science is like peeling an onion. You go deeper and deeper and deeper, and it doesn't stop. It's not like you will get to a right answer.
